The 1800 pack from E-flight is not cutting it for me. What do you recommend for the Bf109? She is a great plane, but the 5-10 min flights are not helping to get my wings... I need to be up there for a bit longer [:D] I am looking at making a king purchase rather soon. [:p]
I'm flying 2200's in my T 28 and pretty happy with the flight times. Although I sometimes forget that the throttle has more than two positions (on and off).
If I recall, the PZ batteries are 12-20C discharge as well. Go for something in the 30-40C range and you will do ok.
